Research Interests

I am interested in investigating the role of cortico-striatal circuits in flexible behaviour in order to understand how disruption of these circuits and their modulation by various neurotransmitters may underpin the inflexible behaviours observed in conditions like Obsessive-Compulsive Disorder.
